Are the domains that are not accepting your email also under your
control on the same machine?

It appears as though the remote machine handling ryska.de's mail gave a
550 response to your MAIL FROM: command as it tried to leave your
server. This is most likely a policy decision of some sort, not a
technical problem.

Contact the postmaster of that domain in a manner that will get your mail
accepted, and inquire about their policy.

Cheers,
